Chris Brown is happy to be taking his relationship with Rihanna slowly.

The 'Turn Up The Music' singer - who rekindled his romance with the 24-year-old 'Diamonds' singer late last year despite still being on probation for beating her in 2009 - is reportedly in no rush to marry her despite their relationship being better than ever.

A source close to the 23-year-old R&B star told ''That isn't even on the radar. No kids, no marriage, none of that is about to pop off. Why some people get married, is a mystery to me.''

Chris has also reportedly resolved his complicated love triangle with his model ex-girlfriend Karrucehe Tran, who recently said she would say no if he proposed to her because it's the wrong time, and has agreed to continue his business relationship with her.

The insider said: ''Chris feels like he's got everything in order with both Rihanna and Karrueche [Tran], and what they have works for them. Besides, come on now, really. Marriage? At 23? At this point in his career and Rihanna's career? It's so far out of the realm of reality so much so that I can't even talk about it anymore.

''As far as settling down, he's already settled. He's got everything he wants; Rihanna loves, Karrueche loves him and he has a relationship with both of them. He and Karrueche got a business relationship, and they're cool together and have fun and s**t, then Rihanna is his main girl and they have a connection that's out of this world. Can't be broken, you know?''

Rihanna was previously said to be eager to take her relationship with Chris public at the Grammy Awards in Los Angeles on February 10.

The 'Stay' singer told friends they plan to make their first public appearance as a couple again at the ceremony.

Rihanna is set to perform at the event and is nominated for three awards including Best Rap/Sung Collaboration, Best Pop Solo Performance and Best Short Form Music Video for 'We Found Love'.
